An action-packed roleplaying game of animals uplifted to serve as humanity's agents among the stars. Welcome to space, the last great wilderness. While humanity has reached the stars, most humans live on Earth and other developed worlds, relying on the brave – or desperate – few to tame this dangerous new frontier. After disastrous experiments with human and AI operatives, the collected nations and mega-corporations of Earth turned to the animal kingdom, genetically modifying and enhancing various species to protect their off-world interests. As humanity extends its reach into Untamed Space, the elite, if expendable, animals of the United Expeditionary Force are the tip of the spear. Untamed Worlds is a military science fiction roleplaying game of anthropomorphic action in which dog-faced soldiers, gorilla commandos, chameleon snipers, octopus gunslingers, and other uplifted animals fight to defend a humanity that looks down on them. The 2D6-based system is simple but dynamic, with success and failure constantly generating new tactical options for players to exploit and challenges to which they must adapt. Whether pacifying alien threats and rebel factions, hunting down rogue AIs, or exploring the unknown, it's never a dull day in the UEF!
